Which is the best description of the process of evolution?
Evolution – The process by which living things can gradually change over time. Inheritance – The process of passing on features from parents to offspring. Species – A group of living things with very similar characteristics.
How long does it take for evolution to take place?
The evolutionary changes we see occurring over a few decades are modest: a cricket that evolves to be silent is still a cricket. When evolution unfolds over longer timescales – thousands or millions of years – it can lead to much larger changes in physical appearance.
Who was the first person to explain evolution?
Evolution is the way that living things change over time. The first person who explained how evolution happens was Charles Darwin with his scientific theory of natural selection. Charles Darwin observed that although individuals in a species shared similarities, they were not exact copies of each other; there were small differences
How did Darwin explain the theory of evolution?
Darwin’s theory explained how every living thing is connected in a family tree that stretches back billions of years to the beginning of life on Earth. These useful terms will help you understand evolution.
Evolution, or change over time, is the process by which modern organisms have descended from ancient organisms. A scientific theory is a well-supported testable explanation of phenomena that have occurred in the natural world.

Where did Darwin find evidence for his theory of evolution?
Findings: evidence to propose a revolutionary hypothesis about how life changes over time Patterns of Diversity Darwin visited Argentina and Australia which had similar grassland ecosystems. those grasslands were inhabited by very different animals.
Who is involved in the process of natural selection?
There is no agent involved in natural selection. Natural selection is a process of elimination Natural Selection is Survival of the fittest Darwin’s Theory of Natural Selection occurs in four steps: Overproduction Variation Competition Selection Overproduction Each species produces more offspring that can survive Variation
